GUN CARRIAGE. I i

To all whom it may concern:

Be it known that I HARRY C. ZIMMER- MAN, a citizen of the llnited States, and a resident of Washington, District of Columbia, have invented an Improvement 1n Gun Carriages, of which the following is a specification.

The invention described herein may be used by the Government, or any of its oflicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

The present invention relates to gun carriages.

The primary object of this invention is the provision of an axle constructed so as to make possible a greater range of traverse of the gun without moving the carriage wheels than is obtainable with the ordinary axle.

Another object of the invention is the provision of an axle bent intermediate its length on an arc WhllC-ll is a function of the length of the trail so that the trail may be traversed on the axle without moving the spade or without any tendency to move the wheels.

With the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed with out departing from the spirit of the invention.

A practical embodiment of the present invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of the carriage axle showing the trail in dotted lines, and

Fig. 2 is a section through the axle.

Referring to the drawings by numerals of reference I have shown an axle, 1, which may be an I-beam or round or of any other suitable shape. The axle 1 is provided with the usual spindles 2 serving as seats for the ea i ge wh e M unt d n t e axle and Application filed September 20, 1923.

Serial NO. 663,908.

(FILED UNDER THE ACT OF MARCH 3, 1883, 22 STAT. L., 825.)

traversable thereon is a trail 3 shown in dotted lines in Fig. 1. The axle in the preferred embodiment of my invention is bent intermediate its length on an are as at 4 the center of which is the spade-end 5 of the trail.

Any suitable traversing mechanism may belemployed for moving the trail on the ax e.

With the ordinary straight axle carriage the amount of traverse is limited to approximately 10 degrees; when more trav erse is desired it is necessary to move the wheels. With the ordinary type of axle, moreover. when the trail is traversed the spade which is attached thereto is moved also; consequently, when traversing the gun is necessary res eating of the trail is necessary also. Hence with the ordinary type of carriage axle when the trail is traversed an initial round is required to seat the spade. With the type of axle described above, however, the trail moves about the spade as a pivot. Hence the spade is not. moved from the ground in the ordinary traversing movement or" the gun; the spade therefore at all times in ordinary traversing movement retains its seat. A firmer positioning of the gun against movement in recoil is therefore possible with my invention than is possible with the type of carriage axle heretofore used. Moreover, with my axle a greater range or" traverse is obtainable without moving the wheels than is possible in the type of carriage heretofore used.

While I have shown my [invention as applied to a single trail gun carriage it is equally applicable to a carriage having a split trail.

I claim:

1. In a gun carriage, an axle, a trail traversable on said axle, said axle bent intermediate its length in a horizontal plane on an are described about the spade end of the trail as a center.

2. In a gun carriage, an axle, a trail traversable on said axle, said axle bent intermediate its length on an are described about the spade end of the trail as a center.
